What This Actually Is
Dr. Simeons' protocol is a very low-calorie starvation diet paired with exogenous hCG injections or drops. The food list itself is absurdly restrictive by design. You're looking at roughly 500 to 800 calories per day, divided into two meals and one small snack, with strict portion limits on specific proteins and vegetables. I've worked with enough clients who tried to modify this diet to make it "sustainable" or "healthy" that I can tell you right now: anything you do to stretch the food list is going to break the protocol. The hCG is supposed to preserve lean mass while the calorie deficit is brutal. Add extra foods and you just get hungry with no additional metabolic benefit.
The Dr Simeons Hcg Diet Food List
The core proteins allowed per day are one of these: 3.5 to 5 ounces of white fish (sole is the only one explicitly mentioned by Simeons), skinless chicken or turkey breast, or lean beef or ham. Eggs are permitted but counted as a protein source, not a separate item. You can have one egg per day if you skip the meat that day. For vegetables, you're limited to one serving per day from an approved list. The standard choices are green beans, cabbage, spinach, celery, tomato, onion, or radishes. Measuring matters. Simeons wrote about raw weight, so if you weigh your green beans after trimming and washing, that's your number. One serving is roughly one cup raw or half a cup cooked, depending on the vegetable's water content. Fruit is basically off the table except for half a grapefruit or one orange once per day during Phase 2 if you're doing the maintenance portion. During the active weight loss phases, you're not eating fruit. Olive oil is not permitted as a cooking fat. You can have a few drops of lemon juice on your vegetables. Salt is allowed but most people on this diet end up with headaches from sodium depletion anyway.
How It Works in Practice
Here's the thing nobody puts in the brochures. The first week feels like withdrawing from food. Your blood sugar is spinning, you're irritable, and the hunger cues are loud. This is expected. The protocol claims hCG suppresses appetite after the first few days, but I've had clients who swear they never got that appetite suppression regardless of whether they used the injection or the homeopathic drops. My workaround for the worst of it was having clients drink warm bone broth between meals. It's not on the official list, but it doesn't add meaningful calories if you strain it properly, and it addresses the mineral deficiency that causes those Week 1 headaches. The client keeps a log entry noting the broth so they don't accidentally double up on permitted foods later. Meal timing is also more flexible than people think. Simeons originally specified two meals with a four to six hour gap, but the actual hormonal mechanism isn't disrupted if you shift that window. What matters is the total daily intake staying within the narrow band. I've seen people do their protein at lunch and their vegetables at dinner with the same results as the rigid schedule.

Common Mistakes and Edge Cases
The most frequent error I see is people weighing cooked food instead of raw. A 4-ounce chicken breast cooked down shrinks to about 3 ounces. If you weigh it after cooking and call it 4 raw ounces, you're underfeeding yourself by about 15 percent. This sounds minor but it compounds over weeks and can slow the scale faster than you'd expect, which then triggers panic adjustments. Another edge case involves the sole fish substitution. Simeons specifically named Atlantic wild halibut as the acceptable alternative to sole, but a lot of commercial "white fish" fillets are tilapia or pollock. These have different fat profiles and may affect ketone production slightly differently. It probably doesn't matter much, but if you're tracking results obsessively, stick to what's listed or use the halibut substitute. Some people try to add cottage cheese or protein powder to get more satiety. This breaks the protein limit and adds calories outside the approved framework. The diet isn't designed to keep you full. It's designed to force your body into a state where stored fat becomes the primary fuel source while hCG theoretically redirects protein breakdown away from muscle tissue. Adding other foods just dilutes the effect.
What This Diet Actually Does and Doesn't Do
The weight loss on this protocol is real but it's not primarily fat loss in most cases. At 500 to 800 calories per day, you're in severe deficit. Most of the early weight drop is water and glycogen. The fat loss component is real but modest compared to what the marketing materials claim. The hCG itself has never been shown in rigorous clinical trials to enhance weight loss beyond what calorie restriction alone produces. The maintenance phase is where most people fail. Simeons' original protocol called for a three-month maintenance period with a specific food list that allows more calories but still restricts certain items. In practice, transitioning from 500 calories to normal eating after prolonged starvation causes rapid regain. This isn't a criticism of the food list. It's a physiological reality. Your leptin levels are crashed, your metabolism is adapted downward, and your hunger hormones are screaming. If you're considering this approach, the realistic expectation is that you'll lose weight quickly during Phase 1 and Phase 2, but the long-term success depends entirely on what you do after the protocol ends. The food list itself is a tool for creating a controlled deficit, not a sustainable eating pattern. I've recommended that clients use it only as a short-term intervention and then transition to a structured whole-food diet with adequate protein and fiber rather than trying to maintain the restrictive list indefinitely.
The biggest practical issue I encounter is the cost and logistics of the hCG component. Legitimate pharmacy-compounded hCG runs around $200 to $400 per month. Homeopathic drops are cheaper but lack the same potency data. Online sources selling hCG for weight loss without a prescription are operating in a legal gray area and product purity is unverified. If budget is a concern, the food restrictions alone will produce weight loss even without the hormone. The combination is what the original research claimed made the difference, but that claim remains contested in the medical literature.
